Sorry for missing that part of the discussion.
If it's not too late to speak my mind, i think that it would be a
shame to have such an awesome and powerful barline interface without
giving users simple way to choose span barline behaviour.

I would imagine the user interface ("syntax") to be like this:
(define-bar-line (a b c) (x y z))
or
(define-bar-line ((a b c) . (x y z)))

where (a b c) are the barlines (mid-system, end-of-system,
beginning-of-system respectively) and (x y z) are the span barlines,
in the same order as barlines.
And it would be nice if
(define-bar-line (a b c) (x))
was equivalent to
(define-bar-line (a b c) (x x x))

cheers,
